1.	Explain the relation between TC,TVC,TFC and TC,MC and MC,AC with diagram
Answer» TVC, TC, and TFC curves in a single diagram.(i) TC is divided into two parts TFC and TVC such that TC = TFC + TVC.(ii) TFC is the overhead cost and it remains constant or fixed whatever be the level of output. TFC curve is a horizontal line parallel to the x-axis.(iii) TVC is cost due to increased use of variable factors like raw material, labour, etc. TVC is inverse S-shaped starting from the origin due to law of variable proportion.(iv) TC is aggregate of TFC and TVC. TC curve is inverse S-shaped starting from the level of fixed cost. The reason behind it shape is the law of variable proportion.
